Specification of Letters Patent.

Application'filed September 17, 1914. ,Seria1No.862,227,

To all whom it mag concern:

Be it known that 1, JOHN C. DOANE, a citizen of the United States, residing in East Long Meadow, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improve- .ments in Type-\Vriting Machines, of which" I the following is a specification.

ways, capable of being set by a key-operated device, and improved detents for said stops; The rack bar is composed of two strips, each strip having, a series of hook-like projections or tongues, which are capable of fit ting togetherwith the two parts of the rack bar engaged, thus efie'cting'a lock joint between said two parts, with clearance spaces between adjacent tongues for the reception and operation of the stops. The 'rack thus has solid partitions or webs between its two parts, to establish. and maintain rigidly the opposed relation of the-rack parts, and to thus provide permanent slideways of a suit-- a I able characterfor the stops, with the length and width of those slideways or clearances accurately established and maintained. One

of the rack portions is provided with a series of grooves or recesses to receive ball detents supported by springs to engage in the recesses in the stops. as the latter, which consjst of plates slidably engaged within the slideways aforesaid, are adjusted therein in the performance of their functions.

lhe stops aforesaid each have a recess to receive a detent when elevated to the inoperative position, and. also a recess for engagement by the detent when moved to the operative position.

Asthe detents may be provided in recesses in the rack arranged in staggered relation therein to avoid weakening the rack, the stops may each have-another recess inorder that they may be operable with detents dilf:

fer'ently located according tothe staggered arrangement;

upper and lower projecting lips to .overhang said rack bar, and a restoring bar, hav .ing a flange to engage under the projecting lips atone end of the stops, is arrangedatog. a be slidable at an angle, whereby lengthwise movement of said -bar,enables' the stops to be all restored in a single'operation.

Other objects andadvantageswill'her inafter appear.

The example of my invention herein contained is illustrated in the operative'relation betweenthe tabulator stops supported by the typewriter carriage, and the column stops mounted upon the frame, as of an Un- The machine parts here shown. include a supporting bracket 1,, which extends from the typewriter carriage, and the bearing portions 2. carrying the rock shaft 3 which.

llhe rack to contain'the vertically mov- "able tabulator] stops 7 consists of the two parts 8 and 9 respectively of the rackbar.

-.These parts each'have, extending from one-I surface thereof, a series of hook-shaped tongues 10. and 11 respectively, said hookshaped tongues being adaptedto fit together and, intprlock to foriny'a series o1"t spannin, 3;

wcifa ihrl wails -between the two parts ,8, and

1 like tongues 10, 11 being interfitted in said Fig. ti'to form a series of spanning webs which thus serve as thel'ateral walls of tlie slideways 12 for 'the stops 7. It will be noted that said hook-shaped tongues, in their interlocking arrangement, are in continuous contacting relation-with each other throughout the entire line of their opposing edges, and unitedly form rigid walls which secure the slideways against variation in the areas they present for theoperation. of the stops. The two parts or members 8, 9 of the rack bar may be united, as'by screws 13 or other desirable connecting means.

The Width of the clearances or, slideways 12 is, of course, PIOPQr-Iy established in the production thereof ,'-so that the stops may be I free to slide within said clearances or slideways excepting as they are detained by, the

operative arresting means.

The stops 7 each consist of a plate of substantially rectangular form, and of dimen- 'slons in Width and thickness rendering them capable of slidably fitting within the clearances or slideways 12. Saidstops 7 have extending lips or flanges l4, 15 respectively at top,'and 'bottom to engage respectively with the upper and lower surfaces of one of the longitudinal portions of the rack at the opposite limits of their vertical movement, so that with the rack members and stops assembled, the stops may not inadvertently leave said rack.

One of the rack longitudinal members, as 8, is provided on its inner surface with a series of transverse horizontal cavities or recesses, one for each stop, and said stops I have in opposed relation to said cavities or recesses coinciding recesses, whereby, with the aid of yieldingly presented ball detents' or the like, the stops may be arrested in different positions of their vertical movement.

As the stops correspond in number With the number of letter-spaces included in a whole line of typewriting, and each' stop requires detent means to arrest it in'operative position, the cavities or recesses are preferably provided in the rack bar or member in staggered relation, to avoid weakening said bar by placingthem in a single continuous row. Thus in the example here shown, the longitudinal rack member 8 has a lower. series of cavities or recesses 16, each containing a ball detent l7 urged outwardly by a spring 18, and also has an upper series of similar cavities 19, each similarly provided with a ball detent 20 having an urging spring 21.

The stops 7-, in order that they may be interchangeably employed in any of the clearance slideways 12, are provided each upon its vertical edge, which is opposed to the detent-carrying longitudinal portion of the rack, with a lower recess or notch 22 and an upper recess or notch 23 adapted respectively to aline with the the case may be when in the operative position. Each one of the stops 7- also has alower notch or recess 24, which is intended to aline with a lower cavity or recess 16 when the stop is restored to its elevated or inoperative position, and obviously, if the stop he in a slideway provided with a cavity or recess 19 of the upper series, then the notch or recess 22 will aline with that cavity or recess 19 to be arrested when said stop is elevated in the inoperative position. Thus the stop provided with three notches 24, 23

and 22 is capable of employment in any one of the slideways herein, and may be arrested by a ball detent of either the upper or lower series in both the downwardly extended operative position and the upwardly extended inoperative position.

In operation, pressure upon the stop in either direction will cause the notch engagement of the stop with the ball detent to press said ball within its cavity against the tension of its spring, allowing said stop to freely slide through the rack until it reaches its adjusted position at which again arrested by its next succeeding notch engaging the same ball detent.

The means whereby the stops 7 are moved to'their operative positions comprise the operating member 6, which has a return hook.- portion 25 arranged centrally of the machine, and adapted when depressed to meet the particular stop 7 that has been alined thereunder through movement of the carriage. The stops 7 are all normally elevated to be inoperative, and when adjusted in operative position, are arranged to cooperate with the usual counter stops, as 26.

\Vhen it is desired to restore the stops 7 to their normal inoperative position, a longitudinal slide bar 27, having a flange 28, which lies beneath the upper lips or flanges l4 bf the stops 7, is shifted longitudinally, in which action said slide 27, having inclined slots.29 engaged by the screws 13 or other fixed guides, rises diagonally and thereby lifts said stops 7 to thus restore them.

The slide 27 has a spring 30 engaged at one end therewith, the other end of said spring having a fixed connection, as at 31,-

memes scope o1 the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:
